Madonna delays tour

Madonna has delayed the start of her tour to make sure it is "perfect".

The 'Like A Virgin' hitmaker - who was set to kick off her 'Rebel Heart' world tour in August - has pushed back her first performances by almost two weeks but has assured fans it will be "worth the wait".

According to Entertainment Weekly, she said in a statement: "As my fans already know, the show has to be perfect. Assembling all the elements will require more time than we realised. I apologise for any inconvenience this may cause my fans. I can promise you this show will be worth the wait. Can't wait to share it with all my Rebel Hearts out there."

The tour is now set to open with a concert in Montreal, Canada, on September 9, with her August 29 and 30, September 2, 5 and 6 shows in Atlanta, Miami and San Juan all having beed moved to late January 2016.

While the 56-year-old singer is busy putting the finishing touches to her show, she is also reported to have been spending time filming a secret music video with Rita Ora.

Madonna and the 24-year-old star are said to have made a "real connection" when they met at various showbiz events and have started working together on the hushed up project.

A source recently said: "It's an incredible coup for Rita to do a vid with Madonna and shows how big she is becoming in the States. They met at showbiz events but had a real connection so Madonna asked her to do it. Rita changed her schedule to be able to do it in an instant."
